To all whom it may concern:

Be it known that I, ABRAHAM L. ADAMS, a

citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Collapsible Tape-Winding Arbors, of which the following is a specification. :1 My invention relates to winding strips of cloth or tape into spools having a central space which permits the spools when removed from the arbor to be formed into an oblong bundle or package.

To this end my invention consists of an arbor adapted to be expanded for the purpose of winding the spool and reduced in size or collapsed to remove the completed spool.

To enable others to understand my invention, reference is had to the accompanying drawings, in which Figure 1 represents the collapsible arbor mounted on a driving-spindle, with a spool of tape wound thereon. Fig. 2 is a side elevation of the arbor expanded and sectional view of the driving-spindle. Fig. 3 is a sectional view of the arbor through line a of Fig. 2 and broken view of the arbor and broken view of the driving-spindle. Fig. 4 is a detail perspective view of the arbor-exanding lever for throwing apart the two lialves of the arbor. Fig. 5 is a view of a spool of tape folded into an oblong package, with a paper-retaining band about 1t. Fig. 6 is a broken side elevation of one part of the collapsible arbor and arm of the other part, showing the position of the lever and spring when the arbor is collapsed.

Its construction and operation are as follows:

The arbor on which the tape is wound comprises the two semicircular parts 1 and 2, operatively connected together by the four links 3, arranged in pairs on each side of the arbor, one 'end of the links being riveted to one .of the halves of the arbor and the opposite or free ends having the elongated slots 4, embracing the pins 5, anchored in the arbor. The part 1 has the central arm 6, having a bore therethrough to receive the drivingspindle 7. The tape-windin arbor may be rotated by the spindle 7 or the spindle may remain stationary and the arbor rotated on the spindle by the spool of tape engaging a rotatable body (not shown) in close proxlmity to the arbor.

V 8 and 9 are collars secured to the spindle 7 on each side of the arbor to prevent end movement of the same.

The arbor is expanded by means of the lever 10, as follows: 11, Fig. 2, is a notch formed in the inner concave face of the part 2 of the arbor to receive the lower edge of the lever 10, while the upper edge of the lever is in contact with the spring 12 secured to the arm 6 by the screw 13. This lever has .the rightangle projection 10*, adapted to prevent its accidental withdrawal, and the projection 10', carrying the knob 14, forms the handle by which it is operated. 15 designates guide-pins secured in the arm 6, extending into and operating freely in the holes 15* in the half 2 of the arbor to assist, in conjunction with the link 3, in keeping the two parts of the arbor parallel with each other. To expand the aror for winding a roll of tape, the handle portion of the lever is carried down a ainst the pin 16, which will bring the edges 0 the lever ard against the bottom of the notch 11 and the spring 12, compressing the latter against the end of the arm 6. This will of course force the two halves of the arbor apart, and the tape 17, Fig. 1, is then wound. If the roll is wound on a solid or non-collapsible arbor, and especially if the roll is large or wound from strips of cloth cut on a bias, it would be a very difficult matter to remove it from such an arbor without pullin it apart; but with my peculiarly-constructs arbor the roll is removed intact by simply throwing the handle of thelever up into the dotted position shown at Fig. 2. This will instantly cause the arbor to collapse, and the roll can be removed intact. The center of the roll will of course have a core equal in diameter to the arbor when expanded, so that when the roll is removed its sides are pressed together into the commercial package shown at Fig. 5 and held together by the paper band 18. This elongated form of the tape takes up less room in shipment than when circular, and heretofore they have been wound in this form around a thin board by hand. With my improved arbor they can be rapidly wound in circular form and then readily collapsed into the elongated form immediately on removal from the arbor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, in a collapsible tapewinding arbor, comprising two semicircular parts operatively linked together, an in- IIO wardly-projecting arm connected with one of said parts, said arm having a bore therethrough for a driving-spindle, a spring on the end of said arm, an expanding-lever located 5 between said spring and the opposite'half of said arbor, means to retain said lever in 0perative positi0n,' all combined and arranged so that, when the lever is thrown in one direction, the two halves of the arbor are IO forced apart to wind a spool of tape, and

' when said lever is reversed, said halves will collapse to permit the removal of the spool, for the purpose set forth.

Signed at Bridgeport, in the county of Fairfield and State-0f Connecticut, this 20th I 5 day of June, A. D. 1904.
